Just wondered what is normal for fuel injection pressure at the rail. Mine has been set to nearly 70psi which seems high. I have had a lot of running problems.
Cheers

70psi would be higher than most people would use.
I assume you have an adjustable reg ?

a very strong possibility this could be your running woes 
whats the motor/spec?Thanks,
Its 4.8L, Merlin heads, mechanical 238cam 10.8:1 cr
I bought the Used Throttle bodies (45mm) complete with the injectors.
There is an intermittent sort of misfire when it happens the engine is reluctant to rev and feels flat.
I am About to upgrade to a 5.0L engine with TA heads. what size injectors do I need?
Cheers
